[0025] As Figs. 1-2As shown in the drawings, in one embodiment, a device for picking induced pluripotent stem cell clones comprises a picking device 1 and a collecting device 2, the picking device 1 is arranged on the collecting device 2, the picking device 1 is used for scribing the clone to be picked, and the collecting device 2 is used for collecting the scribed clone.
[0026] As shown in the drawings, Figs. 1-2 As shown in the drawings, in this embodiment, the picking device 1 comprises a telescopic rod 11, a connecting piece 12 and a picking ring 13. The connecting piece 12 is located between the telescopic rod 11 and the picking ring 13, and serves to connect and adjust the angle, ensuring the stability and convenience of the device; and the connecting piece 12 connected to one end of the telescopic rod 11 is arc-shaped, which can provide a larger range of angle adjustment, allowing the user to easily adjust the angle under different operating environments and space conditions, so as to better adapt to clones of different sizes and shapes.
[0027] Further, the telescopic rod 11 is arranged inside the handle 21, and the switch 211 at the end of the telescopic rod 11 and the handle 21 is connected (similar to the pressing type telescopic mechanism composed of a sleeve, a spring, a pressing rod and a ejector rod in a ballpoint pen, which can realize telescopic function through simple pressing action, ensuring high efficiency and convenience in the operation process, which is not described in detail as prior art). Specifically, one end of the supporting rod 131 is connected to the connecting piece 12, and the other end supports the scribing needle 132, the supporting rod 131 and the scribing needle 132 are perpendicular to each other, and the scribing needle 132 is arranged in groups of 3-6 at equal intervals, thereby forming a picking ring 13 structure like a harrow, the distance and number of scribing needles 132 in each group can be adjusted according to experimental requirements, ensuring the stability and precision of the picking ring 13, and reducing the scribing frequency and damage to the clone.

[0029] Working principle: after determining the selected single cell clone group, press the switch 211 at one end of the handle 21, so that the telescopic rod 11 drives the connecting piece 12 to stretch out with the picking ring 13, then the cross-crossing method is used, that is, first gently draw a line in the horizontal direction, and then draw a line in the vertical direction once, this method can more efficiently and more aseptically obtain high-quality single ips cell colony, after the drawing is completed, press the switch 211 at one end of the handle 21, so that the telescopic rod 11 drives the connecting piece 12 to retract with the picking ring 13, then turn over the scraper 22 to gently collect the clone group obtained by the drawing process, start the micro automatic stirring device 222 on the scraper 22 to mix gently, and then subculture to a new well plate.
